【iOS开发】自定义融云选取位置页面和位置信息页面的导航栏
- 选取位置页面
- 创建 RCLocationPickerViewController 的子类:RCDLocationViewController,可以实现自定义导航栏左右按钮
- (void)viewDidLoad {
[super viewDidLoad];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"自定义左按钮" style:UIBarButtonItemStyleDone target:self action:@selector(leftItemDidPressed:)];
self.navigationItem.leftBarButtonItem.tintColor = [UIColor redColor];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"自定义右按钮" style:UIBarButtonItemStyleDone target:self action:@selector(rightItemDidPressed:)];
self.navigationController.navigationBar.barTintColor = [UIColor blueColor];
}
- (void)leftItemDidPressed:(id)sendr {
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)rightItemDidPressed:(id)sendr {
[super rightBarButtonItemPressed:nil];
}
- 在聊天页子类重写以下方法,并设置代理,present 到子类的对象中。
/*!
扩展功能板的点击回调
@param pluginBoardView 输入扩展功能板View
@param tag 输入扩展功能(Item)的唯一标示
*/
- (void)pluginBoardView:(RCPluginBoardView *)pluginBoardView clickedItemWithTag:(NSInteger)tag {
switch (tag) {
case PLUGIN_BOARD_ITEM_LOCATION_TAG: {
RCDLocationViewController *vc = [[RCDLocationViewController alloc] init];
vc.delegate = self;
UINavigationController *navi = [[UINavigationController alloc] initWithRootViewController:vc];
[self presentViewController:navi animated:YES completion:nil];
}
break;
default:
[super pluginBoardView:pluginBoardView clickedItemWithTag:tag];
break;
}
}
-
聊天页子类需要遵循代理 RCLocationPickerViewControllerDelegate,并实现方法:
/*! 地理位置选择完成之后的回调 @param locationPicker 地理位置选取的ViewController @param location 位置的二维坐标 @param locationName 位置的名称 @param mapScreenShot 位置在地图中的缩略图 @discussion 如果您需要重写地理位置选择的界面,当选择地理位置完成后,需要调用此回调通知RCConversationViewController定位已完成,可以进一步生成位置消息并发送。 */
- (void)locationPicker:(RCLocationPickerViewController )locationPicker
didSelectLocation:(CLLocationCoordinate2D)location
locationName:(NSString )locationName
mapScreenShot:(UIImage )mapScreenShot {
RCLocationMessage locationMessage =
[RCLocationMessage messageWithLocationImage:mapScreenShot location:location locationName:locationName];
[self sendMessage:locationMessage pushContent:nil];
}
2. 位置信息页面
- 创建 RCLocationViewController 的子类LocationViewController
```objective-c
- (void)viewDidLoad {
[super viewDidLoad];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"自定义左按钮" style:UIBarButtonItemStyleDone target:self action:@selector(leftItemDidPressed:)];
self.navigationItem.leftBarButtonItem.tintColor = [UIColor redColor];
self.navigationController.navigationBar.barTintColor = [UIColor blueColor];
}
- (void)leftItemDidPressed:(id)sendr {
[self dismissViewControllerAnimated:YES completion:nil];
}
- 在会话页面重写点击位置消息的回调
/**
- 打开地理位置。开发者可以重写,自己根据经纬度打开地图显示位置。默认使用内置地图
- @param locationMessageContent 位置消息
*/- (void)presentLocationViewController:(RCLocationMessage )locationMessageContent {
// LocationViewController为 RCLocationViewController 的子类
LocationViewController locationViewController = [[LocationViewController alloc] init];
locationViewController.locationName = locationMessageContent.locationName;
locationViewController.location = locationMessageContent.location;
locationViewController.modalPresentationStyle = UIModalPresentationFullScreen;
UINavigationController *navc = [[UINavigationController alloc] initWithRootViewController:locationViewController];
navc.modalPresentationStyle = UIModalPresentationFullScreen;
[self presentViewController:navc animated:YES completion:NULL];
}
- (void)presentLocationViewController:(RCLocationMessage )locationMessageContent {
